WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 514,871, dated February13, 1894. Application filed July 24,1893. Serial No. 481,248. (Nomodel.)

To aZZ whom tr-may concern:

Be it known that I, WILLIAM SCOTT, of Leavenworth, Leavenworth county,Kansas, have invented certain new and useful Improvements inWindow-Screens,of which the following is av full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

Myinvention relates to improvements in window screens; and vrelates tothat class of screens whichwill automatically wind or unwind as the sashis operated, so as to always Voccupy the space left vacant or unoccupiedbetween the sash, and the window-casing.

The primary object of my invention is to provide attachments which maybe easily and quickly operated to allow the screen or sc reens to bemoved without trouble when required.

Furthermore to provide improved means whereby the lower screen strip maybe easily and quickly and also detachably held in position against thelower end or bottom of the window-casing.

A further object of my invention is to produce a window-screen andattachments therefor which are simple, strong, durable and inexpensiveof construction.

To the'above purposes, my invention consists in certain peculiar andnovelfeatnres of construction and arrangement as hereinafter describedand claimed.

In order that my invention may be fully understood, Iwill proceed todescribe it with reference to the accompanying drawings, in which-Figure l, is an inner face view of awindow and showing my screen thereinin operative position. Fig. 2, is a vertical longitudinal sectional viewot' the same, taken on the line of Fig. l. Fig. 3, is an enlargedvertical section of the upper portion of the casing and the-upper sashand showing in operative position .the screen secured thereto and alsoto the upper end of the upper sash. Fig. 4, is a vertical sectional viewtaken on the line fy-/y of Fig. 3. Fig. 5, is a detail perspective viewof the lower corner of the upper sash and showing a spring plate carriedthereby, and adapted to receive the roller of the lower screen. Fig. 6,is a vertical sectional view of the lower corner of the upper sash andshowing a slightly modified form of spring plate carried thereby for theroller support. Fig. 7,' is a detail-perspective view of a portion of aspring roller of the ordinary construction, and showinga sleeve detachedwhich is adapted to be placed upon the end of the shaft to prevent theoperation of the locking dogs. Fig. 8, is a detail perspective view of abearingplate having an elongated opening to receive the Iiattened end ofthe shaft 'of the springroller. Fig. 9, is a detail perspective View ofthe lower end of the lower screen and showing it connected in operativeposition at the bottom of the casing. Fig. l0, is a detail perspectiveview of a portion of the lower` screen and-thestrip secured to its lowerend.

In the said drawings, A designates a window casing, B designates thelower and inner sash and O designates the outer and upper ssY sash;lthese sashes being arranged and adapted toV operate in the windowcasing in the usual manner. A bearing plate D, having the usualelongated opening d, is secured in the upper end of the groove occupiedby the lower sash B, and at the upper end of the similar groove at theopposite side of the casing a recess E is formed.' A plate F i-s securedto cover said recess by screws or other suitable means, and securedby'rivets or other suitable means to the back or outer side of saidplate is the spring-latch G; said latch thus occupying the recess E, andsaid latch is formed at its upper end with an inwardly projecting andhorizontal cylindrical stud g; said stud or 'projection l passinginwardly through a hole or aperturef, in the upper end of the plate F,and said plate is also provided about midway its length with thehorizontal stud g which projects inwardly through an aperture f in theplate F; the object `of this projection g will be hereinafter explained.

A spring-roller,consisting of the shaft H, the spring I, the hollowbody-portion orroller J, the cap K, and the dogs J are all of the usualconstruction and arrangement, but in order to hold dogs J out ofvoperative position with reference to the notched shaft H, I provide acylindrical sleeve L, and this sleeve IOO is slipped upon the projectingend of the shaft II so that it shall be interposed between said shaftand the dogs J and also shall bear against the disk M by which said dogsare carried. A screen section N has one end secured to the outer side ofthe roller J, and is wound thereon in the usual manner and has itsopposite end secured by nails or rivets or in any other suitable mannerto the inner ro side of the upper sash-rail c, the upper end of the ribor flange a., of the casing separating the groove h, of the lower sashfrom the groove c', of the upper sash, being cut away at its upper endand rounded at a', for this purpose, and so that the screen will notbind thereon when thesash is operated; the squared or flattened end h,of the shaft Il, entering the elongated recess CZ, of the bearing D, and

the cylindrical stud g, entering a cylindrical 2o recess 1', formed inthe opposite end of the roller J.

From the foregoing, it will be seen that as the upper sash is loweredthe screen will be unwound from the roller J, and will screen or coverthe space between the upper rail of the descending sash and the upperend of the casing, and when the said sash is raised the screen sectionwill be automatically rewound upon the roller in the usual manner.

In order to prevent mosquitoes or iiies entering the room between theupper end of the casing and the upper side of the screen roll Z, whichas will be readily Seen dwindles or becomes smaller as the sash ispulled down- 3 5 Ward, a springplate O is provided; this plate O beingsecured to the upper end of the casing and pressing against the outerside of the screen-roll for its full length, so that as the roll becomessmaller the spring-plate will al- 4o ways be in contact with saidscreen-roll so that the space there-between and the upper end ot' thecasing will be closed. When it is necessary or desirable that thisscreen and roller be removed it is disconnected from the upper sash railby withdrawing the nails or rivets by which it is secured thereto, andapplyin g pressure upon the projection g so that the stud g shall beforced outwardlyand disengaged from the recess j of the roller J, 5owhen the said roller and screen maybe easily and quickly removed fromthe casing. If desired, the stud g maybe dispensed with, and the stud g,forced from engagement with the recess j, by introducing a nail or anysuitable article through the opening f so that pressure may be broughtto bear upon the spring latch G. In order that the lower portion of thewindow may be screened, I provide a spring-plate having an elongatedopening 6o similar to the plate D, and a spring-plate D having a hole oraperture D2. A spring-roller having a screen section secured thereon asalready described, has its opposite ends secured in said bearing platesat the lower ends of the upper sash,and has the lower end of said screensection secured to a transverse and horizontal strip P by screws, rivetsor other suitable means. This strip is provided at intervals withapertures or holes p, and these holes or apertures are adapted to engagethe horizontal and outwardly projecting portions q, of retainer-pins Qsecured to the window-sill. The strip is also provided preferaly with aknob or handle R.

Referring to Fig. 10, I show the lower end of the screen clamped betweenthe ends ot` the sheet metal strip P; which is first bent upwardly toforln two sides, and then the upper portion of the sides is bentinwardly and downwardly to form a narrow space therebetween, in whichthe end of the screen section is to be clamped.

From the foregoing, it will be seen that as the upper sash is loweredthe lower and cx tended screen will be wound upon the roller carried atthe lower end of the upper sash, and at the same time the upper screenwill be extended and unwound from its roller so as to close the spacebetween the upper rail of the said sash and the upper end of the windowcasing, and that as said sash is raised the upper screen will be rewonndupon its roller and the lower screen will be extended or unwound toclose the space between the window-sill and the lower end ot' the saidsash.

From the above description, it will be seen that I have produced awindow screen or screens which are simple, strong, durable andinexpensive of construction.

Ilaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

I. A window screen apparatus, comprising a spring-retracted roller ofthe usual construction, and a cylindrical sleeve mounted upon the shaftof said roller so that the dogs thereof shall not engage with thenotches of said shaft, and a screen section secured to and wound uponsaid roller, and having its opposite end secured to the upper rail ofthe sash, substantially as set forth.

2. In a window screen apparatus, the combination with a spring retractedroller, and a bearing plate having an elongated opening to receive theflattened end of the shaft of said roller, and a screen section woundupon said roller, of a bearing plate secured in the casing at theopposite end of said roller, and having openings or holes therein, and aspringlatch having a cylindrical stud passing through one of saidopenings and engaging a recess in the adjacent end of the roller, andhaving a stud projecting through the other hole or opening of said plateand adapted to be pressed inwardly to disengage the stud from therecessed end of the roller, substantially as set forth.

In testimony whereof I affix my signature in the presence of twowitnesses.

WILLIAM SCOTT.
